The UN Security Council has expressed outrage at the abduction of hundreds of girls by Islamist militants in Nigeria.
Boko Haram said it was behind the kidnapping of more than 250 schoolgirls in northeastern Nigeria on April 14 and has threatened to sell them into slavery.
The UN Security Council on May 9 demanded their immediate release and threatened to take action against the insurgents.
Boko Haram's five-year insurgency is aimed at reviving a medieval Islamic caliphate in modern Nigeria, whose 170 million people are split roughly evenly between Christians and Muslims.
